This ground connection must be made using a system bonding jumper and formed at or before the first disconnecting means of the system. The neutral conductor is typically the grounded conductor connected to the system...

Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor
Forming a ground connection with a transformer is easy. This ground connection must be made using a system bonding jumper and formed at or before the first disconnecting means of the
Bonding is not to be confused with grounding. Two pieces of equipment bonded together does not necessarily mean both pieces of equipment are grounded. However, it assures that the
The grounded conductor, typically the neutral, is the return path for the fault current from the panel back to the utility transformer. The connection made by the main bonding jumper forces the fault current
Clear directions in 250.148 specify that all of the equipment grounding conductors present in a box or enclosure are required to be connected, regardless of the circuit with which they are associated.
This article takes an in-depth look at the main and system bonding jumper and the role it plays in grounding and bonding, how we size it up and install it.
An equipment grounding conductor passing through the box without a splice is not required to be joined inside the box to others that are spliced in the box.
Correct grounding of services depends upon understanding the definition and role of the grounded conductor. The neutral conductor is typically the grounded conductor connected to the system''s
Some inspectors require the grounding electrode conductor connection to the service neutral conductor to be made at the meter socket enclosure, while others insist the connection be made only within the
